The Clean Air Act has worked: Jonathan Samet, MD
Since the passage of the Clean Air Act (CAA) more than 40 years ago, the air quality in urban areas such as Los Angeles has greatly improved. Once unthinkable, the San Gabriel mountains can be seen from LA.
Jonathan Samet, MD, Chairman of the Department of Preventive Medicine at USC, wrote an essay in the NEJM about the CAA and upcoming decision that must be made by the EPA. He also explains why air pollution is medically harmful.
